CAPONIZING'INSTRUMENT Filed July 14, 1928 1 Patented Sept. 24-, 1929 UNlTED STATES PATENT GFFICE Application filed July 14,

This invention relates to surgical instruments, and its general object is to provide an instrument primarily designed for caponizing fowls in an easy and expeditious manner, in a single operation, without breakage to the testicle and with minimum pain and liability of injury to the fowl, with the result the testicle can be removed in its entirety and slips or stabs prevented.

A further object of the invention is to provide a caponizing instrument that can be conveniently manipulated, cuts and carries the testicle through the incision after it has been removed, simple in construction, inexpensive to manufacture and efficient in operation and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the sev-- eral views, and in which:

Figure 1 is a perspective view of the instrument forming the subject matter of the present invention.

Figure 2 is a fragmentary enlarged front elevation thereof showing the same in use.

Figure 3 is a similar view taken at right angles to Figure 2.

Figure 4 is a bottom plan view.

Referring to the drawings in detail, the reference numeral 1 indicates the handle of the instrument, and as shown, the handle is relatively narrow and somewhat elongated.

Formed integral with the handle is the body 2 of the instrument which as shown is substantially cup-shaped and is provided with open ends, with portions disposed upon opposite sides of the handle. The body is rounded from its connection with the handle and is formed with a substantially flatbottom which has arranged therein a substan tially Vshaped recess or re iii int chan net IIE'W OPLLEADTS, LOUISIANA INSTRUMENT 1928. Serial NO. 22:2,767.

It will. be noted that one portion of the body 2 extends a greater distance beyond its connection with the handle than the other portion, and the V-shaped recess enters this enlarged portion and terminates into the other portion, as suggested in "Figure 4 of the drawings. The walls of the body adjacent the recess are curved slightly upwardly and the w=lls of the recess are curved accordingly so as to provide a relatively sharp cutting edge l.

Formed in the sides of the body and extending to the juncture of the bottom thereof with the side walls are substantially triangle shaped openings 5 which are disposed in opposed relation with respect to each other.

The body has its hollow portion arranged at rightangles to the handle, with the result very little difliculty will be experienced in disposing the testicle in the body in the manner as illustrated in Figure 3 of the drawings. When the gland is arranged in the body, the attaching membranes will be dis posed through the V-shaped recess, and due to the fact that the walls of the recess are curved upwardly, an upward pull will sever the gland from the attaching membranes, with the result the instrument not only removes the gland in its entirety, but carries the same through the incision. It will be obvious from the novel form of the recess 3, and the walls thereof, that an upward pull of the instrument with the latter arranged at a slight inclination toward the apex of the recess 8, that the grip on the gland at its juncture with the membranes will increase during the pulling action.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

lVhat I claim is:

1. A caponizing instrument comprising a relatively narrow elongated hand].

. 3' ll?" shape br y formed integral witl" said l l and. a: rug substantially :iil t ranged at right angles to said handle, said bottom being formed with a substantially V- shaped recess entering one edge thereof and terminating adjacent its opposite edge and said recess being provided with substantially sharp cutting edges.

2. A caponizing instrument comprising a handle, a hollow body having open ends and a substantially flat bottom arranged below said handle and extending at rightangles with respect thereto, said bottom being formed with a relatively narrow V-shaped recess extending from one end thereof and terminating adjacent its opposite end, said bottom being curved upwardly toward the walls of the recess, said walls being likewise curved to present substantially sharp cutting edges, and triangle shaped recesses "formed in the sides of said body.

3. A caponizing instrument comprising a handle, a hollow body formed with said handle and having a substantially flat bottom extending at right angles with respect to said handle, said body having one end portion projecting a greater distance laterally of the handle than the other end portion and extending into one end of said bottom which is likewise extended, said bottom being provided with a substantially V-shape recess disposed inwardly from the last mentioned end thereof and terminating adjacent its opposite end and said recess having upwardly curved walls for the purpose specified.

In testimony whereof I affix my signature.
